The Rotational Move (or Move) component generates a forced angular position according to an input vector. The input vector has three components: position, velocity, and acceleration. They must be consistent with each other.

These conditions do not apply to all applications. For example, if the position-dependent terms of a mechanical system are calculated only, you can provide $\mathrm{\phi }$ and set the angular velocity and the angular acceleration to zero.

The Use Support Flange boolean parameter enables a support flange on the housing. When true (checked) the support flange must be connected in the drawing. When false the component is internally fixed to ground.

$\mathrm{\phi }\=u_1$

$\stackrel{\.}{\mathrm{\phi }}\=u_2$

$\stackrel{..}{\mathrm{\phi }}\=u_3$

$\mathbf{if}\mathrm{Use\; Support\; Flange}\mathbf{then}{\mathrm{\tau }}_{\mathrm{support}}\=-\mathrm{\tau }$

$\mathrm{\phi }\={\mathrm{\phi }}_{\mathrm{flange}}-\{\begin{array}{cc}{\mathrm{\phi }}_{\mathrm{support}}& \mathrm{Use\; Support}\\ 0& \mathrm{otherwise}\end{array}$
